Incorporating Fingerprint Readers Into Keyboard

Biometric based access control is getting more widely accepted and implemented to the point that we are now seeing fingerprint sensors or readers that can be attached to or built into a computer to provide increased security for the computer itself and applications that run on the system.

While these devices are designed to provide a strong and convenient method of validating users, following limitations exist:

While the devices typically allow users to register multiple fingers, only one of them is used for verification process.

Users may be reluctant to using typical fingerprint sensors and having their fingerprint information stored on computers thinking that the readers are storing actual digital image of their finger tips that can be stolen and abused.

The proposed invention will provide a way to collect users' fingerprint information while addressing the issues discussed above.

The proposed invention idea involves incorporating multiple fingerprint scanners or sensors into keyboard as shown in Figure 1 below:

Using the fingerprint readers on keyboard, we can read fingerprints from multiple fingers at once instead of just one finger. However, because of the reduced surface size of sensor, only partial fingerprint from each f...
